There were a few advantages to the Seiki sliding doors, and a few drawbacks too. When not needing it, which was about half the time for us, it was nicely out of the way. It was a bit finicky, and though easily adjusted, I did seem to do it a few times a year, mostly to keep it opening fully all the time. I was a great option given that the curve of the door would not easily allow a swing type screen door.
That said, I very much look forward to using the new one in the 2017 models. I have heard lots of good things about it.
Either way, not going to fuss about it, it is what it is, and I can live with that and enjoy going camping.
